Power Machines has manufactured the second guide vane for the Mainskaya HPP RusHydro
Leningradsky Metallichesky Zavod produced the second guide vane for the hydropower unit (HU) No. 3 of the Mainskaya HPP. The device passed functional tests and is being prepared for shipment. Delivery of the equipment to the plant is scheduled for June 2021.
The guide vane is one of the largest elements of the HU. It is designed to supply water flow to the impeller and regulate its flow through the turbine, depending on the load and rotation speed of the hydropower unit. One of its features is the use of modern anti-friction material in the support units that does not require lubrication during operation. In addition, the new design of the upper ring allows the HPP personnel to replace the bearings and sealing elements of the lower pins of the blades without complete disassembly of the device, which improves maintainability and reduces the customer's costs for unit maintenance.
The contract for the supply of the hydroturbine equipment for the Mainskaya HPP was signed between Power Machines and RusHydro in September 2018. The scope of obligations of Power Machines includes the manufacture and supply of equipment for the hydroturbines of units No. 1, 2, and 3 of the Mainskaya HPP and the installation supervision services.
As a result of the project implementation, the efficiency of the units will be increased.
To date, Power Machines has manufactured a guide vane, an impeller, an oil-filled unit, and turbine automation equipment for the HU No. 3, as well as spare parts for the hydroturbines of the HUs No. 1, 2, and 3.
